SPOKANE VALLEY, Wash. - General Dynamics Itronix announced today a full-featured, fully rugged
computer in the "ultra-mobile" category that is designed to meet the portability and durability needs of
industrial, commercial, military and government customers. The GoBook MR-1 is a two-pound, fullfunction
rugged notebook measuring 4.3 inches by 6 inches, allowing users to work on a portable,
lightweight, reduced-footprint machine, with a superior outdoor viewable display, wherever duty takes
them.

"We are seeing market interest in smaller, more portable devices that still have all the functionality of a
full-fledged notebook," said David Daoud, research manager, United States Quarterly PC Tracker and
Personal Systems, IDC. "The GoBook MR-1 is likely to find a receptive audience among the highly mobile
workforce in segments such as government, utilities, communications, and field services in need of a fully
functional PC in a ruggedized ultra-small form factor."

Mike DiBiase is vice president of computing technologies for General Dynamics C4 Systems. "This ultramobile
notebook was developed with the needs of both defense and commercial users in mind," DiBiase
said. "The development and successful launch speaks to the company's ability to address the rugged
computing needs of customers in virtually all conditions and operating environments."

The 5.6-inch SVGA-W GoBook MR-1 runs with the full Windows XP Pro operating system (and Vista by
the end of 2007), which helps to reduce training and support costs by providing users and IT management
with a familiar interface. The GoBook MR-1 also features the new patent-pending DynaVue
touchscreen display technology as an option. This innovative display technology, announced in May,
provides dramatically improved outdoor screen viewability while optimizing battery life and processing
power for ultra-mobile end users.

"The GoBook MR-1 new notebook form factor provides extreme portability and mobility, without
sacrificing any of the features of a full-size rugged notebook, and best of all, it will also run on Vista
utilizing the latest in today's technology," said John Ball, general manager, U.S. Systems Builder,
Microsoft. "I am excited that a key manufacturer is delivering such innovation to users who require
computing solutions in many extreme environments."

GoBook MR-1 Product Features
The GoBook MR-1 packs the capabilities of a full notebook computer into a clamshell notebook small
enough to fit into a coat pocket. The GoBook MR-1 is as powerful and rugged as it is ergonomic and
portable, sporting the lightest and smallest footprint of any rugged, ultra-mobile notebook. The GoBook
MR-1 also provides the user multiple navigational input devices through a touchpad interface as well as a
micro joystick for optimal flexibility in cursor navigation and selection.

Performance
The GoBook MR-1 is built with state of the art technology, giving it the power to leverage multi-threaded
applications, graphics commonly found in field deployed workforce environments such as public safety and
field service, or military, and boost overall speed and performance:

Ergonomics
Built for fully rugged mobility, the GoBook MR-1 features:

Ruggedness
The GoBook MR-1 provides the highest level of durability, designed to meet or exceed MIL-STD 810F for
temperature and drop, as well as vibration testing. The unit is also IP-54 rated for dust and humidity
making it suitable for use in harsh and unpredictable environments. The GoBook MR-1 was designed to be
rugged from the inside out and meant to survive in harsh, unpredictable environments. The unit features
shock-mounted display and key internal components, and is housed in a magnesium alloy clamshell case
with impact absorbing bumpers. The GoBook MR-1 will be vehicle-mount crash-tested for in-vehicle
safety. Additionally, the GoBook MR-1 will be compliant with Hazardous Locations (HazLoc) UL1604
Class I, Division 2, Group A, B, C & D.

Wireless Connectivity
Like all GoBook notebooks, the GoBook MR-1 features the ability to manage multiple embedded wireless
radios and standards, with upgrade protection to accommodate new wireless standards as they emerge:

Security
The GoBook MR-1 was built to offer unmatched data and asset protection, with support for multiple user
and network authentication options. Security features include a user-removable 40 GB or optional 80 GB
shock mounted hard drive (with optional solid state hard drives in 16 GB and 32 GB), fingerprint reader,
TPM 1.2, and file/folder locking capabilities, and stealth-mode keyboard and display settings for secure
environments, as well as configurable access to all input/output devices for data transfer restriction and
multiple asset protection features.

Modular flexibility
The GoBook MR-1 is engineered to include modular, innovative expansion module ("slice") architecture.
The expansion module enables users to integrate legacy I/O interface functionality and additional
accessories. The expansion module/slice can be customized for additional expansion such as PCMCIA. An
expansion module ("slice") is required for the 80 GB hard drive option as well as the TPM 1.2 security
feature.

Availability, /Pricing and Service
The GoBook MR-1 base configuration will be generally available in September 2007 at the suggested USD
retail price of $4,450. The unit is backed by a three-year warranty and supported by end-to-end customer
care services including value programs like "one-call" Mobility Help Desk for enterprise and government
customers. The notebook may be purchased through a General Dynamics Itronix channel partner or directly
by calling (800) 441-1309.
